PubMed Abstract:
A series of quinoxaline inhibitors of c-Met kinase is described. The postulated binding mode was confirmed by an X-ray crystal structure and optimisation of the series was performed on the basis of this structure. Future directions for development of the series are discussed together with the identification of a novel quinoline scaffold.
